PROBLEM TO BE SOLVED: To provide an ultrasonic probe 2 that includes a delay material 8 and a transducer array 4 having a plurality of transducer elements 6 installed on the delay material 8, and is used for inspection of a workpiece 44. SOLUTION: The plurality of transducer elements 6 of the transducer array 4 are installed on a curved outer surface of the delay material 8. Since the transducer elements 6 in the transducer element array lie at equal distance from the center of curvature radius 14 of the delay material 8, sound waves simultaneously generated by two or more of the transducer elements 6 simultaneously reach the radius center also called an origin 16. Reflective sound that is received by the transducer in the array 4 and passes an index point is not affected by time delay resulting from the geometric structure of the delay material 8.
